Female donors: 85.8% of all female donors tested in Mar’25 vs. 85.1% tested in Aug’25 were NH White
Male donors: 85.2% of all male donors in Mar’25 A1c testing campaign vs. 85.1% in Aug’25 were NH White
Conclusion: No signficant differences in test counts by race, gender were observed between Mar’2025 and Aug’2025
in spite of significant difference in total number of donors tested between these two months.

For all racial groups, the number of younger donor (20 or less) were signficantly lower in August compared to that in March.
For hispanic donor count, a nearly uniform distribution of donor age were observed during Aug’2025.i.e., donors counts by age between ages 16-50 were nearly same for each age.
For Asian/other races, middle aged donors were tested more than younger or older donors.
For Black and White donors, the older (50+) age groups were tested more than younger or middle aged.

4.5% of NH White donors tested in Mar’2025 vs. 4.9% of NH White donors tested in Aug’2025 had A1c% in the diabetes range. (Donor population in these two months were unique, i.e., donors tested in March were different from those in August).
Similarly, 7.2% vs. 9.5% of NH Black donors tested in the months of Mar’2025 and Aug’2025 had A1c% in the diabetes range.

Between race/ethnicity groups, the Black donors have a relatively higher median A1c% for any age group during each test month.
White donors have the lowest median A1c by age group.
Between March and August donor cohorts, clinically significant differences in median A1c value, for the same race and age group, were not observed.
For donors from the same race and age group, a difference of 0-0.1% in the median A1c values between test months were observed.
